The Trek down sleeping bag brings the comfort of a tapered-rectangular mummy shape and the versatility of a dual-zip ventilation system to wherever your travels may take you. The full-length side zipper and secondary foot box zipper allow you to increase ventilation or open the Trek completely flat like a comforter, and the quality down will keep you warm and snug on chilly nights.

The broader mummy cut gives you room to move inside the bag, regardless of your sleeping position. A Regular Wide model is available for those who really appreciate the extra wiggle room.

Light and compact, the Trek might just become your favorite trekking / backpacking / travel / camping / down sleeping bag.
